WAVETEK 4920 Alternating Voltage Measurement Standard

The Wavetek 4920 Alternating Voltage Measurement Standard is designed to replace the traditional AC/DC Thermal Transfer Standard in high-accuracy AC measurement applications. Fully traceable measurements can be made with uncertainties equal to or better than all but the most specialized standards with the speed, ease of use, and convenience of a single, programmable, intelligent device. AC Voltage; Ranges: 3 mV to 1000 V in 3, 10, 30 sequence. Resolution: 100 nV, 71/2 digits. Operating Range: From 30% to 110% of Nominal Range Value. Remote Programming: IEEE-488.2. Options; 10: 3 mV to 100 mV Ranges. 50: Wideband Module to 50 MHz.

dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
